JENOPTIK JENar F-Theta Field Lens 255mm 114x114 1030-1080nm Marking

This JENar series F-Theta field lens (laser scanning focusing lens) from JENOPTIK, Germany, features a 255 mm focal length and 114*114 mm working field, serving as the general-purpose workhorse for fiber laser marking and engraving systems. The lens combines a bright blue anodized aluminum front ring with a matte-black rear barrel, utilizing multi-element high-performance optical glass to deliver low-distortion, high-uniformity focusing across the full field in the 1030 nm - 1080 nm range.

The F=255 mm configuration provides an excellent balance between field size and spot quality, designed to pair with 10-14 mm aperture scanners for marking various metal and non-metal materials. As a genuine German import with full traceability, it integrates seamlessly with SCANLAB galvo scanners.

Frequently Asked Questions
Q: What is the actual marking field of F=255 mm?
A: This model covers 114*114 mm – the standard configuration of fiber marking machines; effective field varies with scanner aperture.
Q: Which lasers and scanners does it pair with?
A: Suits 1030-1080 nm fiber lasers and SCANLAB intelliSCAN / basiCube class 10-14 mm scanners.
Q: How long do the coatings last?
A: With normal use and cleaning, coating life matches the machine; avoid contamination and direct laser damage.
Q: Can it replace the lens in my existing marking machine?
A: It uses a standard mount; most equivalent F-Theta lenses are directly interchangeable. Send your current focal length and mount spec and we will confirm.
Q: Warranty and after-sales?
A: Genuine import with warranty per contract; technical support and lens inspection services available.
Q: Lead time?
A: German import; typical 1-2 weeks (depends on stock and logistics); bulk orders can be pre-stocked.
